Answer:
weight = 5, 6.5, 7.2, 9, 16
cost = $2.50, $3.25, $3.60, $4.50, $8.00

12+2x-10=3x-5
12-10 +2x=3x-5
2+2x=3x-5
Move +3x to the other side. Sign changes from +3x to -3x.
2+2x-3x=3x-3x-5
2+2x-3x=-5
2-x=-5
Move +2 to the other side. Sign changes from +2 to -2.
2-2-x=-5-2
-x=-7
Multiply by -1 for -x and -7
(-1)(-x)=(-1)(-7)
x=7
Answer: x=7
